Documentation

The following functions are currently implemented:

• assertArraysEqual: Compare two arrays and pring out a message telling us if they match or not.
• assertEqual: Compare two values and print out a message telling us if they match or not.
• assertObjectsEqual: Compare two objects and print out a message telling us if they match or not.
• countLetters: Take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly: Takes in an array and an object. It will return an object containing counts of everything that the input object listed.
• eqArrays: Take in two arrays and returns true or false, based on a perfect match.
• eqObjects: Take in two objects and returns true or false, based on a perfect match.
• findKey: Takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value.
• findKeyByValue: Takes in an object and a value. It should scan the object and return the first key which contains the given value.
• flatten: Take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• head: Retrieve the first element from the array.
• letterPositions: Take in a string and return all the indices (zero-based positions) in the string where each character is found.
• map: Take in an array and a callback function and return a new array based on the results of the callback function.
• middle: Take in an array and return the middle-most element(s) of the given array.
• tail: Take in an array and return everything except for the first item (head) of the provided array.
• takeUntil: Return a slice of the array with elements taken from the beginning until the callback returns a truthy value.
• without: Return a subset of a given array, removing unwanted elements.
